How to use custom analyzers in azure search to get the partial text search?

Question

I am new to the Microsoft Azure. I want to know how to do the partial text searching. I created azure cosmosdb and added some documents to the database through c#(To Insert the documents into the cosmosdb I followed the example in the given link: https://docs.microsoft.com/en-us/azure/cosmos-db/sql-api-get-started) and I created azure search resource, Import the data from cosmosdb to created index in azure search. I am getting the result for full-text search example.

query:
https://mysource.search.windows.net/indexes/documentdb-index/docs?api-version=2017-11-11&count=true&search=madhu  
Result:
  {
    "@odata.context": "https://mysource.search.windows.net/indexes('documentdb-index')/$metadata#docs(*)",
        "value": [
            {
                "@search.score": 1.4182854,
                "id": "Madhu_3",
                "LastName": "Madhu",
                "Parents": [
                    "{\"FamilyName\":null,\"FirstName\":\"Madhu\"}",
                    "{\"FamilyName\":null,\"FirstName\":\"Kalathuru\"}"
                ],
                "Children": [
                    "{\"FamilyName\":null,\"FirstName\":\"Henriette Thaulow\",\"Gender\":\"female\",\"Grade\":5,\"Pets\":[{\"GivenName\":\"Fluffy\"}]}"
                ],
                "IsRegistered": false,
                "rid": "W1wPAPoraMUDAAAAAAAAAA=="
            }
        ]
    }

But If I tried with partial text(like "ma") it reverts empty value. I gone through azure micro soft documents I found that I have to use custom analyzers for partial texting but I did n't understand how to use that?. Can anyone suggest me how to apply the custom analyzer to the fields? Thanks in advance.

You could use custom analyzers for this by creating multiple tokens from each word. However, It would probably be better in this case to just use a wildcard search. Alternatively, Autocomplete and search suggestions are also useful to help users create the best query to find what they are looking for.
